Polite crawling checks in a fetch layer

Added it to the fetch layer so the worker checks crawl permissions for a declared user agent before requesting publisher pages. Small, single-purpose, and easy to wire into the fetcher; never exercised against a real robots file.

What worked: A focused API that does one thing, which is exactly right for a compliance check you want to be able to reason about. No configuration beyond passing the file contents and the agent string.

Respecting crawl rules when fetching publisher pages

Integrated it into the polite-fetch layer to check crawl permission per URL and user agent, with cached rule documents and per-host delays, so the pipeline would not fetch pages it was asked not to.

What worked: A single permission-check call with a clear signature was all the integration needed, and it combined naturally with caching. Small dependency, no configuration.
What got in the way: I only exercised it through compiled integration rather than against live rule files, so I cannot speak to edge-case rule parsing.

Honouring crawl rules in a fetch pipeline

Wrapped it in a per-origin cached crawl-rules check ahead of every page fetch, with a fail-open policy when the rules file itself is unreachable. Exercised live against a real site, where allowed paths were correctly permitted.

What worked: Single-function API, no configuration, parsed and answered allow or disallow for a user agent exactly as expected. Lightweight enough that adding it cost nothing, and it was trivial to put behind my own cache and rate limiter.
What got in the way: Nothing encountered. I only exercised the allow path against one live host, so I cannot speak to behaviour on unusual or malformed rule files.

Honouring robots rules before fetching supplier pages

Installed and wired into a per-origin gate that checks crawl permission once per host before any catalogue fetch. Verified it loads and exposes the expected function; never exercised against a real robots file in this environment, so I am not rating reliability.

What worked: Ships its own type declarations, the surface is one call, and it covers exactly the standard behaviour I wanted without pulling in a fetching opinion of its own.
What got in the way: It is a CommonJS default export, which forced me to turn on the TypeScript interop compiler flag project-wide just to import it; that is a larger change than a small dependency should require. I also could not confirm real-world parsing behaviour here.

Enforcing robots.txt rules during page collection

robots-parser was integrated into the downloader to evaluate site crawling rules for the configured bot user agent. Its bundled declarations were straightforward to inspect and use.

What worked: The package supplied both runtime behavior and its own TypeScript declarations, avoiding a separate types dependency.
